Drug-dispensing contacted lenses could offer new hope to people suffering from glaucoma, which causes blindness, after they were found to be at least as effective as eye drops.

Researchers say that the lens, which is designed to deliver medication gradually, may improve the treatment of patients who struggle with eye drops, which can be imprecise and difficult to self-administer.

It is estimated that more than 500,000 people in England and Wales have glaucoma, a build-up of pressure on the eye, but many more people may suffer from the condition without having been diagnosed.

Doctor Joseph Ciolino, an ophthalmologist at Harvard Medical School, said: "We found that a lower-dose contact lens delivered the same amount of pressure reduction as the latanoprost drops, and a higher-doselens, interestingly enough, had better pressure reduction than the drops in our small study.

"Based on our preliminary data, the lenses have not only the potential to improve compliance for patients, but also the potential of providing better pressure reduction than the drops."

Glaucoma is the leading cause of irreversible blindness in the world.

While there is no cure for the condition, medications are designed to lower pressure in the eye with the goal of preventing vision loss.

Currently, the medications are delivered in the form of...read more at Telegraph
